FUNCTIONS The functionality of this leak detection system for modified atmosphere packaging is quite simple. Modified atmosphere packages normally contain CO as part of the protective atmosphere other products produce CO by themselves. The LEAK-MASTER is using this CO as a trace gas. Packages can be tested for leaks directly after the packaging process. Using this method ensures that the product remains entirely undamaged and dry after testing. The LEAK-MASTER administrates the specific settings for up to,00 products as well as name, password and barcode for up to 0 users. The selection of tested products and the user log-on is controlled via touch screen or by optional barcode reader. The quality system LEAK-MASTER checks leak tightness of packages to avoid any quality risks and meets the requirements of the HACCP concept. With a special WITT control software package the measurement documentation can be integrated into the overall quality system. All results including date, time, product details and user name can additionally be sent to MS-Excel. For data transfer WITT is offering the industrial standard Ethernet. Via this interface the LEAK-MASTER can be connected to the company network on demand also wireless by WLAN. CONCLUSION LEAK-MASTER by WITT Leak testing of food packages containing CO. Non-destructive, fast and exact. BENEFITS Finds the smallest of leaks Highly sensitive, very fast CO sensor No need for costly helium Fast change of products For flexible and solid packages Intuitive use No calibration required No skilled personnel needed Stainless steel frame Various chamber sizes For sample testing of: Single packages Cartons E boxes OPTIONS Barcode Reader WLAN GAS CONTROL CENTER Software for data administration Product and user administration Parameters (product and user) File administration (MS Excel compatible) Measuring data administration Automatic (periodic) or manual Data transmission to MS Excel Multi-device Data exchange with multiple LEAK-MASTER ISO 000 approval for food safety

FUNCTIONS LEAK-MASTER MAPMAX features non-destructive detection of even the smallest leaks using CO as trace gas a 00 % testing method connected directly to the packaging process. Thus not a single leaking package gets to the customer. LEAK-MASTER MAPMAX places the packages or shipping case in the test chamber. A settable vacuum is produced, resulting in pressure differences between the tested package and the testing chamber. CO escapes through smallest leaks and the CO concentration within the chamber rises. The highly sensitive sensor reacts and detects even smallest leaks. After each test cycle the chamber is flushed with air and the tested package is forwarded to following systems. If a leak has been detected, several potential free contacts are available for communication with other equipment which for example could trigger an alarm or a pusher to sort out a faulty package. Important facts for the achievable cycle time are the CO concentration within the package, the leak size and the chamber size. CONCLUSION LEAK-MASTER MAPMAX by WIT T In-line leak detection system based on CO for up to cycles per minute. Unique worldwide. BENEFITS Non-destructive leak detection and sealed seam testing for flexible and rigid single packages or shipping cases No costly returns 00 % protection against order or reputation loss Functionality like LEAK-MASTER but fully automatic Installation directly into the packaging line Unique worldwide high frequency up to cycles per minute Suitable for all packages containing CO Highly sensitive, very fast CO -Sensor No need for costly helium Six standard sizes for all customers requirements as well as customised versions available OPTIONS Reject system Barcode Reader WLAN ISO 000 approval for food safety

FUNCTIONS LEAK-MASTER EASY features detection of even the smallest leaks without the need for trace gases. The package is placed into the chamber filled with water, the head space above the water level is evacuated using a venturi vacuum (compressed air) system. The package immersed in water inflates. At the location of a leak air or filling gas escapes as a visible stream of bubbles. CONCLUSION LEAK-MASTER EASY by WITT Leak detection without trace gases also for vacuum packages. Cost effective and easy. BENEFITS Short testing period (< 0 sec.) For all flexible and rigid kinds of packs (Food-, pharmaceutical-, industrial and other packages) No trace gas required in package No calibration required Simple rigidity test realisable in dry chamber Easy to-use intuitive system no special skills required Various chamber sizes available Easy installation and start-up Low maintenance Easy to clean perspex housing 8 No vacuum pump necessary No electrical connections, operation using compressed air OPTIONS Available for vacuum packages Available for altitude simulation test (air cargo) ISO 000 approval for food safety
